Flooding

Road Flooding Recession & Drainage Monitoring

Road Flooding Recession & Drainage Monitoring turns existing road cameras into a continuous read on standing water. It tracks when flooding starts and when the water begins to drop, flags locations where the water is not draining as expected, and ranks recurring flood points so crews know where to look first. It is built for road authorities, city operations centers, and emergency response teams who need to reopen roads safely and target drainage work.

VLM output

A wet suburban intersection where standing water covers the low-lying road surface and partially submerges the base of the yellow-and-black bollards on the traffic island. Across the four frames the water gradually recedes, with the pooled area shrinking and more dry pavement and road markings reappearing, while parked cars remain stationary and no traffic passes.

Customer challenges

1

Operators learn that a road has flooded from scattered calls and reports, long after the water has risen.

2

Deciding when a road is safe to reopen depends on someone driving out to look.

3

A blocked drain looks the same as a slow-draining road on a status board, so the real fault goes unnoticed for hours.

4

Repeat flood locations are known informally by experienced staff and are hard to prove when maintenance budgets are set.

Customer benefits

Teams see flooding start and recede as it happens, so closures and reopenings are timed on evidence.

Crews are sent to the sites where water is not clearing, instead of checking every reported location.

Drainage faults surface as an alert rather than as a pattern someone notices later.

Maintenance planning is backed by a record of which roads flood again and again.

Before & after

Before Flood reports arrive by phone from drivers and patrols. After — with Linker AI Nexa The system flags rising water on camera and notifies the control room.
Before Staff drive to a site to check whether water has cleared. After — with Linker AI Nexa Recession is tracked from the camera feed and updated continuously.
Before A blocked drain is found once the road stays wet longer than expected. dispatch and road-closure decisions After — with Linker AI Nexa Slow or stalled drainage raises an anomaly alert on its own.
Before Reopening a road is a judgment call made under time pressure. After — with Linker AI Nexa Reopening decisions rest on an observed water level trend.
Before Recurring flood points live in staff experience and old work orders. After — with Linker AI Nexa Repeat locations are ranked from recorded flood history.
